IMPROVEMENT IN SPRING ATTACHMENTS FQR CRADLES.

Specification forming part of Letters Patent No. 171,798, dated January 4, 1876; application filed November 6, 1875.

To all whom it may concern:

Be it known that I, HENRY S. HALE, of Philadelphia, Pennsylvania, have invented an Improved Spring Attachment for Cradles, Chairs, 85e., of which the following is a specitieation:

The objectof my invention is to provide the body of a cradle or seat of a chair with aiexible support, which will permit the said cradle or chair to be vibrated in any direction 5 and this object I attain in the manner which I will now proceed to describe, referencebeing had to the accompanying drawing, in which- Figure 1 is a perspective view of the inverted body of a cradle with my improvement, and Fig. 2 a transverse section.

The body of the cradle consists, in the present instance, of the base A, two railed sides, B and B', and opposite end pieces D D, and on the under side of the body, at opposite edges ot'the same, are two strengthening-strips, a a. E is a central pin, attached to, or formin ga part of, a hub,d, from which project fourradial spring-arms-two of them, m m, extending to the strengthening-bar a on one side ot' the body of the cradle, and two ot' them, mk m', to the strengthening-bar a on the opposite side, each arm having, in the present instance, a slot, through which a set-screw passes into the said bars. The base ofthe body of the cradle is situated a short distance above the springarms, so that it can have a restricted vertical movement, and, owing t0 the arrangement of the spring-arms, (shown in Fig. 1,) the body is at liberty to vibrate in any direction, the extent of vibration being limited by an annular projection, e, on the stand Gr, in which the central pin E is arranged to turn.

Each corner-piece f of the body of the cradle may be provided with a leg, h, hinged at w, as shown in Fig. 3, these legs being retained by any suitable device in an elevated position when the body of the cradle has to be vibrated in the manner described, and being turned down and secured by a locking device, so as to form one of four legs, the latter 'resting on the licor, and converting the body ofthe cradle into a crib incapable of rocking. 4

Fig. 4 illustrates my invention asapplied to a chair, m m being the spring-arms, similar to those above described, and the extent of vibration being limited by the arms or projections e e', in place of the annular projec tiene, as in Fig. 2.

I claim as my inventionl. The combination of the pin'E, adapted to a suitable stand, G, and the spring-arms m m m m', attached to the body of a cradle or seat of a chair, all substantially as and for the purpose herein set forth.

2. The combination ot' the central pin E and its four spring-arms, attached tothe body ot' a cradle or seat ot' a chair, with a stand, Gr,

adapted to the said pin, and provided Withan annular stop, e, all substantially as set forth. In testimonyA whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY S. HALE.
